RConvLog - multiplatform CONVLOG replacement

Purpose

Rconvlog (Rebex Internet Log Converter) converts web server log files from a native log format into NCSA format. It can be very useful especially when you use a log analyzer which does not support a native IIS format or a W3C Extended format (e.g. excellent Webalizer).

IIS is shipped with a similar program called convlog, which is able to convert web server log files into NCSA format. However using Microsoft convlog causes some problems: original convlog does not transfer browser agents and referrers. When used with FTP log files, all uploaded files are ignored.

Rconvlog deals with all those difficuilties.

Features

  • converts web server log files from IIS to NCSA format
  • runs on Windows, Linux and FreeBSD
  • supports browser agents
  • supports referrers
  • when used with FTP log files both uploads and downloads are logged (Microsoft's version converts only download)
  • a call format is compatible with Microsoft convlog. Rconvlog can in most cases be used as an out-of-the-box replacement or a bugfix release of the original ;-)
  • a powerful and efficient DNS lookup and a caching mechanism

Usage

 
Usage: rconvlog [options] 

LogFile Options: 
-o <OUTPUT directory> default = current directory 
-c <HOSTNAME file cache> 
-t <ncsa[:GMTOffset]> 
-d convert IP addresses to DNS 
-w overwrite existing files (default is append)
-b <0|1|2|3> = how to log bytes sent 
   0 - compatible with convlog (default) 
   1 - bytes sent server-client only (download) 
   2 - bytes sent client-server only (upload) 
   3 - bytes sent both upload and download 
-n YYYY-MM-DDTHH:NN:SS = ignore records older than specified datetime 
-h H = ignore records older than H hours 

Examples:
rconvlog file.log -w
rconvlog *.log -w -d -t ncsa:+0800
rconvlog w3c*.log -w -d -c c:\temp\cache.txt
rconvlog abcd*.log efgh.log -n 2002-01-01T00:00:00
